| 摘 要： | 传统磁共振波谱成像时间太长 ,不能应用到临床。发展快速波谱成像方法是必然的。目前有 7类快速波谱成像方法 ,它们都来自快速 MRI成像方法。本文对传统波谱成像和 7类快速方法分别作了介绍 ,并且展望如果把 MRI中任意轨迹图像重建方法用于波谱成像 ,将能够设计出速度更快的波谱成像数据采集脉冲序列。

| Abstract: | The required time of conventional magnetic resonance spectroscopic imaging technique is too long to be applied to clinic. It is necessary to develop the fast methods for magnetic resonance spectroscopic imaging. Nowadays there are 7 kinds of methods presented,which come from MRI techniques. In this contribution the conventional spectroscopic imaging and 7 sorts of fast spectroscopic imaging are elaborated. It is envisaged that more rapid imaging techniques will be designed,if these arbitrary trajectory reconstruction methods in MRI are applied to spectroscopic imaging. |
